COVERING FOR STEAMPIPES,`&,C.

SPECIFICATION forming part of Letters Patent No. 234,417, dated November16, 1880. Application filed September 17, 1880. (No model.)

To all 'whom it may concern .Be it known that I, JANE MERRIAM, ofMilwaukee, in the county of Milwaukee, and in the State of Wisconsin,have invented certain new and useful Improvements in Coverings forSteam-Pipes, Boilers, Src.; and I do hereby declare that the followingis a full, clear, and exact description thereof'.

My invention relates to steam boiler'and pipe covering, and will befully described hereinafter.

In the drawings, Figure 1 isa side View ofa portion ot' my improvedcovering with its Various layers exposed. Fig. 2 is a cross-sectionthereof, and Fig. 3, a like section of the casing with which I proposeto cover steam-pipes before they are placed in the logs used by theSteam Supply Company. Fig. 4 isa gasket, which I propose placing aboutthe pipe and between the ends of the logs.

The casing F is of wire-gauze generally, and is iilled with mineralwool, the sides being held'apart by braces of wire c, bent into a seriesof connected Us, as shown in Fig. 2, and in uprightpipes these bracesmay be quartered and placed in various parts of the covering to preventthe mineral wool from falling down and packing, and to prevent the ,woolfrom falling through onto the pipe I place a layer ot' asbestus paper,C', between the wool and inner wall,D, ofthe casing. This casing alonemakes a complete covering, but it may be found expedient at times tointerpose a layer of paper, C, and wire-gauze B between itand the pipe.

After the casing is on I secure its edges together by double-pointedtacks b, or by wires a passed about the whole.

In placing the sections of my covering I may interpose between each ofthem a gasket, Fig. 4, of wire-gauze filled with mineral wool,

but I generally propose to interpose it between the ends of the logsused by the steamsupply and about the pipes which are inserted therein,but it will be found useful wherever great heat is to be encountered. Ofcourse, instead of making the easing F of wi regauze, I may make it ofsheet metal without departing from the spirit of my invention.

The sections are all made in the shop and shipped complete in such shapethat an unskilled workman may put them on, and when on I propose to wrapit with cemented canvas.

I am aware that incombustible and nonconducting material has been placedabout boilers, pipes, Ste., and bound to them by wiregauze, and such Ido not claim.

WhatIdo claim as my invention isl. In a covering for pipes and boilers,a casng of wire-gauze filled with mineral wool and adapted for beingplaced about the pipe or boiler and secured thereon, substantially asdescribed.

2. In a covering for pipes, boilers, te., a casing ot' wire-gauze iilledwith mineral wool, having a layer ot' asbestus between the wool and itsinner wall, and adapted to be placed about a pipe or boiler, as setforth.

3. In a covering for pipes, boilers, 85e., a casing Jlilled with mineralwool, in combination with bracing-Wires c for holding the walls apart,as set forth.

4. A gasket composed of mineral wool encompassed by wire-gauze on allsides, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this23d day of August, 1880.

JANE MERRIAM.
